Re: Protecting your golf clubs and preventing scratchesI have iron covers on my clubs, I don't think it's idiotic at all. Although before I had them, I will admit I laughed at the people with iron covers. Now I'm a convert.
Also, the reason I got them was only partially due to protecting from scratches and dings. The main reason I got them was to minimize bag noise. I usually walk and the sound of the irons banging into eachother right behind my head was ANNOYING. Also, I felt like I was disturbing other people on the course with my loud bag chatter.
Anyway, if you want to avoid nicks and scratches as much as possible WITHOUT iron covers, I would clean (at least brush off) after every shot, and wash them after every round.
